Cat Back Kourstronic BMW E60 M5

The new system has arrived

The legend of the BMW E60 M5 is known for its high-torque and high-revving V10 engine and its sound that reminds you of Formula 1 cars. At Koursatronic, we decided to challenge the impossible and create an exhaust system that surpasses even the famous Eisenmann system, combining performance, incredible sound, and flexibility in all conditions. The result? A system that redefines the exhaust experience for the E60 M5 and takes it to a whole new level!

An exhaust worthy of the legendary V10 engine

Our engineers worked on the system with a unified vision: to make the exhaust highlight the character of the S85 engine and give you full control over the sound. With our new system, you'll hear the honesty of the V10 with a true Formula 1 sound, with the ability to adjust the tone according to your mood and situation.

Full sound control with valve flaps

The system comes with vacuum-operated valve flaps – which means you have full control over the sound! When the valves are closed, the sound is quiet and refined for the highway or city driving. And when you open them? Here comes the V10 beast, with a sound that will daze everyone around you!

Superior to all competitors

The secret lies in the professional design of the large central section, precisely engineered to give you the best airflow and a balanced, clean sound. The system reduces turbulence inside the pipes and focuses all the power to deliver a loud, pure, and rich sound, fitting the sporty character of the S85.

Unmatched exhaust experience

This is not just a simple modification, this is a radical change to your driving experience! E60 M5 owners no longer need to dream of the Eisenmann system – the Koursatronic system is the new standard for every car enthusiast and lover.
